Anthropic’s new AI model, Claude Opus 5.5, stands out with its performance increase and cost advantages of up to 40%.
Anthropic is attracting attention in the technology world with its new AI model Claude Opus 5.5 features. The company states that this new model offers significant improvements in performance, accuracy, and communication capabilities.
Claude Opus 5.5 offers a faster and more efficient structure compared to the previous generation Opus 5 model. According to Anthropic data, the model generates responses 30 percent faster while reducing operating costs by approximately 40 percent.
Performance Increase with Claude Opus 5.5
Users experience a clearer and more understandable communication experience, especially during long work sessions. Early testers emphasize that the model’s syntax is more natural and followable.
A software engineer notes that the model writes like a suitable colleague and adheres to the defined rules. In performance tests, Claude surpasses models such as Opus 5.5, Fable 5.1, Opus 5, GPT-6 Astra, and GPT-5.6 Sol.
The model leads in criteria such as agentic coding, information processing, and visual graphic recognition. In areas such as business processes and scientific research, it ranks second, immediately after GPT-6 Astra.
Anthropic also proves the model’s success in real-world scenarios. For example, a tester was able to review and correct a 200,000-line codebase in less than three hours.
The same process took more than 20 hours with Opus 5 and cost significantly more tokens. There is also a significant increase in efficiency when converting software languages.
In the process of switching from C to Rust, Opus 5.5 delivers results faster than Fable 5.1, with a time of 9.5 hours. The company states that this model is the most powerful performing model they have tested to date.
Security and Accessibility
Anthropic states that the new model not only provides speed and cost advantages, but also strengthens security. Claude Opus 5.5 has a local classifier that scans every action before execution.
This system allows the model to develop stronger defense systems compared to previous versions. It offers a more resistant structure against prompt injection attacks, especially in areas such as coding, tool use, and web browsing.
Security tests conducted by Gray Swan note that the model has one of the lowest attack success rates. On the pricing side, significant reductions in API costs are noteworthy.
A discount is applied to entry tokens from $5 to $4 per million, and to exit tokens from $25 to $20. Similar improvements have been made to cache read and write costs.
In addition to developers, Claude Opus 5.5 is also available to regular users. Users with Pro, Max, Team, and seat-based Enterprise plans can access the new model with five-hour usage limits.
How do you think these cost and performance advantages offered by Claude Opus 5.5 will affect competition in the AI world?
